A huge rainfall deficit ensured August 2021 was the third hottest August in the country in the past 120 years but it was also marked by the Ridge area in the capital breaking its 24 hour rainfall record for the month.

As far as temperature was concerned, the monthly average maximum, average minimum and mean temperature over all India for the month of August during 1901-2021 shows the average ‘maximum temperature’ over all India was third highest (31.75 degree C) and average ‘minimum temperature’ was eighth highest (24.39 degree C) while the ‘mean temperature’ over all India was third highest (28.07 degree C) since 1901, making it the third hottest August.

“The observed average maximum, average minimum and mean temperature for the country as a whole during August 2021 are 31.75 degree C, 24.39 degree C and 28.07 degree C respectively, against the normal of 31.09 degree C, 24.01 degree C and 27.55 degree C based on period 1981-2010,” said the India Meteorological Department’s (IMD) weather analysis for August.

The overall rainfall deficit (24% below long period average) had led it to be the lowest August rainfall in the country in the last 12 years (after 2009).

So far during period 1901-2021, August 2021 was the 6th lowest after 1920 (32.5% below LPA), 2005 (28.4% below LPA), 2009 (26.5% below LPA),1913 (25.6% below LPA), and 1930 and 1993 when it had 25.2% below LPA.

Only 28 stations reported extremely heavy rainfall

The IMD said certain stations recorded ‘very heavy’ to ‘extremely heavy’ rainfall with six of them including Delhi Ridge, Car Nicobar, Aizwal, Bundi, Thanjavur and Shivpuri reporting their 24-hour respective record rainfall in August.

“There were only 28 stations which reported extremely heavy rainfall”, said the IMD in its analysis. There are over 4,000 rainfall recording stations in the country. Referring to the impact of weather events in August, the IMD noted that a total 121 persons lost their lives while 28 persons got injured during the month.

Chennai:11.06.2020

After cloudy skies brought from some relief from the sweltering summer heat on Wednesday, weathermen said the city has chances of rainfall or the first thunderstorm of the season in the next two days, while clouds continue to engulf the skies as a low pressure over Bay of Bengal is gathering strength. Temperatures will rise again by weekend, as the system will intensify and move into the land.

IMD has forecast, “The sky condition likely to be generally cloudy. Light to moderate rain is likely to occur in some areas in the city in the next 48 hours.”

On Wednesday, the city was mostly cloudy with temperatures at 34.1°C in Nungambakkam and 34.4°C in Meenambakkam, which were 2.6°C and 2.9°C below normal. Humidity too was at 60% in Nungambakkam and 62% at Meenambakkam.

Weather bloggers said the skies were overcast on Wednesday with mostly high clouds which were at an altitude of 20,000 feet. These clouds mostly bring traces or light rainfall. Cloudy skies could continue while as the low pressure gathers intensity over Bay of Bengal, which could take another 48 hours. According to IMD’s regional inference, a low pressure over eastcentral and adjoining west central Bay of Bengal persists with associated cyclonic circulation extending up to mid-tropospheric level tilting southwestwards with height. It may move westnorthwestwards and become well marked during the next 48 hours “The wind convergence, which could bring rain, was happening over the sea. What we had was high clouds. The city will see an overcast sky on Thursday as well,” said weather blogger Pradeep John.

As southwest monsoon is progressing to other regions in the country, the system over Bay of Bengal may bring spells over the west coast due to the drag it creates over the next few days before it intensifies and moves towards central India. On Wednesday, some parts of west Tamil Nadu like Coimbatore recorded light rainfall at 0.2mm and coastal areas like Karaikal 25.3mm and Nagapattinam at 16.4mm. IMD has forecast light to moderate rain likely over isolated places of Tamil Nadu, Puducherry and Karaikal till June 14.
